[Geography of genetic processes in human populations: gene migration in Northern Eurasia (European region)].
A method of transformation of census data on population migration into data on gene migrations is proposed. Based on the 1970 Population census of the former Soviet Union, coefficients of effective direct migration m in 91 population of the oblast size in the European part of Russia were estimated. Each coefficient was calculated as the geometric mean of effective values for the island and stepping-stone models of population structure. A map of the geographic distribution of gene migrations was constructed. Low rates of gene migrations were shown to be associated with steppe-forest and deciduous forest zones. Mean coefficients of gene migration estimated from the observed data for the European region and from the map data weighted by the area sizes were respectively m = 0.0156 +/- 0.0011 and m = 0.0232 +/- 0.0011. In view of the fact that the census data were collected simultaneously, all m values were multiplied by 2.8 in order to estimate gene migration rate per generation. Correlation analysis of gene migration coefficients m and genetically effective population sizes Ne demonstrated that these population parameters are independent. This analysis showed the reverse relationship between the rate of gene migration into a population and population density, in particular, density of settlements within the population area.
